STREET-CAR M OTO R.

SPECIFICATION forming part of Letters Patent No. 556,105, dated March 10, 1896.

Application filed October 19, 1894. Serial No. 526,394. (No model.)

To aZZ whom it may concern.-

Be it known that I, CECIL L. SAUNDERS, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certainn ew and useful Improvements in Street-Car Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in street-car motors; and it'consists in certain features of construction and in combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a motor embodying my invention; and Fig. 2 is a top plan of the same. Fig. 3 is an elevation showing gear M that transmits motion to gear N from one of the gears K.

Referring to the drawings, A represents the frame of a motor-car truck, B the axles, and C the car-wheels.

D represents the cylinder of a gas or gasoline engine provided with supply and exhaust pipes, cooling-jacket and water-pipes, all aranged in the usual manner of this class of engines.

The engine is mounted in any suitable manner upon a frame E, that is suitably supported from the axles of the truck, supporting-frame E being preferably of such construction as to bring the cylinder of the engine in a plane located as little above the axles as is practicable.

A preferable construction is exhibited in the drawings, wherein the cylinder of the engine has laterally-projecting flanges d bolted,

as at cl, to supporting-frame E, and the latter comprises side members 6 arranged at a suitable interval apart between the axles upon which the supporting-frame of the engine is mounted. Said side members 6 of 5 supporting-frame E are provided with journal-boxes 9 that afford bearing for engineshaft G. Shaft G is provided with a crank G between members 6 of frame E, which crank is operatively connected by means of a rod h with the piston H that operates within the cylinder of the engine. The engineshaft extends at either side of frame E, and is provided with a fly-wheel I at any suitable point. Two gears K are operatively mounted upon the engine-shaft at a suitable interval apart and preferably just outside of frame E. Oneof said gears meshes directly with a gear L loose on the driving-axle, and the other is adapted to communicate motion by means of an intermediate gear M to a gear N, also loose on the driving-axle, intermediate gear M being preferably supported by a bracket on rigid with the adjacent side of frame E.

By the construction just described it will be observed that the driving-axle is caused to drive in the one direction or the other, according as operative connection is established between said axle and the one or the other of gears L N. Engine supporting frame E at the end that is mounted upon the driving-axle is reduced in width, as at E, to accommodate the location and operation of clutches 0 upon the driving-axle at opposite sides, respectively, of said reduced portion of 7 5 frame E, a clutch being provided for each gear L and N to establish or interrupt operative connection between the respective gear and driving -axle. Frictionclutches are shown employed in the case illustrated, the one mem- 8o ber of each clutch being rigid with the respective gear and the companion member of the clutch being operatively mounted upon the driving-axle. Operative connection between the two members of either clutch is established by means of any suitable lever mechanism. (Not shown.)

By the construction hereinbefore described it will be observed that the motor-car will cease to be driven when both clutches are op- 0 erated to interrupt operative connection between the drivin ggears and driving-axle, and that the driving-axle, and consequently the motor-car, will be moved in the one direction or the other, according as operative connec- 5 tion by means of the respective clutch is established between the driving-axle and the one or the other of driving-gears L N.

By means of the particular arrangement of parts hereinbefore specified, wherein the Ice clutches and axle-driving gears are mounted upon the axle, the wear and strain on the parts are not only reduced to a minimum, but great economy in space is obtained, which is desirable.

What I claim is- 1. The combination with a mot0rtruck, of a frame suitablysupported between the wheels of opposite sides of the truck, an engine mounted upon said frame with the engineshaft located in suitable proximity to the driving-axle and extending at either side of the en gine-supporting frame, two gears loose upon the driving-axle, two gears operatively mounted upon the engine-shaft at opposite sides, respectively, of the aforesaid frame and two gears loosely mounted upon the driving-axle adjacent to the different engine-shaft gears, respectively, one of said loosely-mounted gears meshing directly with the adjacent engine-shaft gear, an intermediate gear establishing operative connection between the other loosely-mounted gear and the other 011- gine'shaft gear, and two clutches operatively mounted upon the driving-axle between the two gears upon said axle, said clutches being adapted to establish and interrupt operative connection between the diiterent axle-gears, rspectit ely, and the axle, substantially as shown and described.

2. The combination with a motor-truck, of. a

frame, E, suitably supported by the axles of the truck and reduced in width at the end supported by the driving-axle, substantially as indicated, an engine mounted upon said frame with the engine-shaft located in suitable proximity to the driving-axle and extending at either side of the engine-supporting frame and provided with a fly-wheel, two gears loose upon the driving-axle at opposite sides of the reduced portion of said frame, respectively, and clutches located between said gears and frame for operatively connecting and disconnecting the gears and drivingaxle and suitable means operatively connected with the engine-shaft and operatively connected with the gears on the driving-axle in. such a manner that the driving-axle shall be driven in the one direction or the other according as operative connection is established between the driving-axle and the one or the other of the axle-driving gears, substantially as set forth.

In testimony whereof I sign this specification, in the presence of two witnesses, this th day of August, 1894.

CECIL L. SAUNDERS.
